like Zone Alarm 5.x ?
I have two computers set up to a home network running windows XP. I have a Viewsonic wireless router, but I have wired connections. They normally have internet speeds of nearly 4 mbps. All of a sudden (over night) my speed on one, and only one, of my computers dropped to 750 kbps. I've tried rebooting the computer,router and modem, setting my router back to default settings and starting over, running 4 different antispyware programs on the effected computer, running an antivirus scan, booting in safe mode, switching router ports, and nothing seems to work. My other computer is running just fine off the same router.
I think it's got to be either a computer hardware or software issue, since the other computer is fine using the same modem and router. Everything was OK when I went to work in the morning and the computer seems to run OK, but IE and Firefox are excruciatingly slow.
Could it be my network card? Any other ideas?
